Margaret Gilbert explores the phenomenon referredto in everyday ascriptions ofbeliefs to groups. She refers to this type ofphenomenon as ``collective belief'' andcalls the types of groups that are the bearersof such beliefs ``plural subjects''. Iargue that the attitudes that groups adoptthat Gilbert refers to as ``collectivebeliefs'' are not a species of belief in animportant and central sense, but rathera species of acceptance. Unlike proper beliefs,a collective belief is adopted bya group as a means to realizing the (...) group'sgoals. Unless we recognize that thisphenomenon is a species of acceptance, pluralsubjects will seem prone to changetheir ``beliefs'' for irrelevant reasons, andthus frequently appear to act in anirrational manner.

The financial community does not seem to have shifted to greater sustainability, despite increasing awareness and concerns around social and environmental issues. This article provides insights to help understand why. Building on responsible investment data from the U.K. financial press between 1982 and 2010, the authors examine the collective beliefs which financial actors rely on to take decisions under uncertainty, as a way of understanding the status of and implications for RI mainstreaming. The analysis of collective (...) class='Hi'>beliefs through five periods of RI leads us to define two theoretical dimensions—justifying RI and practicing RI—that characterize how mainstream actors collectively make sense of RI. The authors’ analysis reveals that the RI collective beliefs currently do not provide a favorable environment for RI mainstreaming and need to be taken into account when discussing the value of sustainability.

What is it for a group to believe something? A summative account assumes that for a group to believe that p most members of the group must believe that p. Accounts of this type are commonly proposed in interpretation of everyday ascriptions of beliefs to groups. I argue that a nonsummative account corresponds better to our unexamined understanding of such ascriptions. In particular I propose what I refer to as the joint acceptance model of group belief. I argue that (...) group beliefs according to the joint acceptance model are important phenomena whose aetiology and development require investigation. There is an analogous phenomenon of social or group preference, which social choice theory tends to ignore. (shrink)

One of us [Gilbert, M.. “Collective Belief and Scientific Change.” Sociality and Responsibility. Lanham, MD: Rowman & Littlefield. 37-49.] has proposed that ascriptions of beliefs to scientific communities generally involve a common notion of collective belief described by her in numerous places. A given collective belief involves a joint commitment of the parties, who thereby constitute what Gilbert refers to as a plural subject. Assuming that this interpretive hypothesis is correct, and that some of the belief (...) ascriptions in question are true, then the members of some scientific communities have obligations that may act as barriers both to the generation and, hence, the fair evaluation of new ideas and to changes in their community’s beliefs. We argue that this may help to explain Thomas Kuhn’s observations on “normal science”, and go on to develop the relationship between Gilbert's proposal and several features of a group of physicists working on a fundamental physical theory called “string theory”, as described by physicist Lee Smolin [Smolin, L.. The Trouble with Physics. Mariner Books: New York.]. We argue that the features of the string theory community that Smolin cites are well explained by the hypothesis that the community is a plural subject of belief. (shrink)

The development of collective beliefs via informational and reputational cascades represents a way of shortcircuiting the difficulties related to the collective action of ‘latent groups’ to ensure the promotion of their particular interests. This essay focuses on the protection of consumers, whose quality of the life has never been so high, despite the prevalence of hazardous products.Rationally ignorant individuals form their opinions by conforming to those of others; this can take two forms, either by consolidating their personal (...) judgement or their private information, or by pure conformist behaviour. It may even be that such individuals rarely hesitate, if necessary, to admit beliefs that they do not actually hold in order to avoid being ostracised by others. ‘Latent groups’ activists manipulate the process of formation of beliefs in order to bring about a predominant opinion on any given issue. Armed with the asset of the prevailing opinion, pressure can be exerted upon politicians in view of obtaining regulations and subsidies which would protect the ‘latent group’ of which they claim to be the representatives.This is the new face of collective action where the “politically correct” replaces physical violence or the strike. This way of shaping public opinion could have a beneficial outcome if it were not founded on erroneous information or led to a violation of individual rights due to regulation. However, this not the case. The very leitmotif of this method is, in fact, to bring about regulation which, by definition, violates private lives. In any case, it is dangerous because the manipulation of public opinion by these activists implies an intensive use of rhetoric, distorting the perception of risk, which in turn involves the circulation of misleading information in order to create a cascade modifying public opinion in favor of the proposed regulation, rather than informing the public on the potential risks and letting them insure freely against it if they judge to do so. But for the activist the end justifies the means. Thus, this manipulation of public opinion is a danger to the notion of modern democracy, already so sensitive to the pertaining to the majority.La formation des croyances par le biais des cascades d’information et de réputation est un moyen de courtcircuiter les difficultés liées à l’action collective des groupes latents pour assurer la promotion de leurs intérêts particuliers. Dans le cadre de cet essai est analysée la protection des consommateurs, dont la valeur de la vie est élevée, contre les produits à risque.Les individus rationnellement ignorants forment leurs opinions en se conformant aux croyances des autres, soit pour conforter leur jugement personnel ou leurs informations privées, soit par conformisme pur. Il se peut même que les individus n’hésitent pas, s’il le faut, à afficher de fausses croyances, pour ne pas être frappés d’ostracisme par les autres.Les activistes des “groupes latents” manipulent le processus de formation des croyances pour faire émerger une opinion majoritaire sur un problème spécifique. Grâce à cette opinion majoritaire ils vont pouvoir faire pression auprès des hommes politiques pour obtenir une réglementation et des subventions à leur propre profit dans le but de protéger le “groupe latent” dont ils prétendent être les représentants. Ce sont les nouvelles formes d’action collective où le politiquement correct remplace la violence physique ou le piquet de grève.Cette façon de former l’opinion publique pourrait avoir des conséquences bénéfiques si elle n’était pas fondée sur des informations erronées et si elle n’aboutissait pas à une violation des droits individuels par la réglementation. Or ce n’est pas le cas. Elle est faite justement pour faire émerger une réglementation qui par définition viole la vie privée des gens. Par ailleurs, elle est dangereuse parce que la manipulation de l’opinion publique par ces activistes implique un usage intensif de figures de rhétorique, de biais dans la perception des risques, de diffusion de fausses informations dans le but d’enclencher une cascade qui va modifier l’opinion publique en faveur de la réglementation et non pas dans le but d’éclairer le public sur les véritables risques encourus, la fin justifiant les moyens.Cette manipulation des croyances est alors un danger pour la démocratie politique contemporaine déjà si sensible à l’opinion majoritaire.

What do we mean when we say that some group believes something? Do we simply mean that all the members of the group believe it, or are we acknowledging the existence of some kind of group agent? According to Margaret Gilbert, talk about group mental states refers to the specific kind of agreements she calls joint commitments — that is, to collectively believe something means to be committed with others to believe it. In my article, I will first present Gilbert’s (...) approach in more detail but will ultimately show that this approach is problematic and will refute it. I will briefly consider the most common solution to the problems Gilbert’s account faces, which lies in replacing collective beliefs with acceptances, but I will show that this solution will not do either. The solution I will then present will be based on Daniel Dennett’s intentional strategy, which is a method of interpreting the things around us and predicting their behaviour by treating them as rational agents with relevant intentions. I will try to show that all the problematic cases of collective belief can be explained by applying the intentional strategy to the groups in question. (shrink)

According to Margaret Gilbert, two or more people collectively believe that p if and only if they are jointly committed to believe that p as a body. But the way she construes joint commitment in her account – as a commitment of and by the several parties to “doing something as a body” – encourages the thought that the phenomenon accounted for is not that of genuine belief. I explain why this concern arises and explore a different way of construing (...) joint commitment, in order to avoid the concern. This leads me to propose a revised Gilbertian account of collective belief, according to which two or more people collectively believe that p if and only if they are jointly committed to p as true.

The author develops and elaborates on her account of collective belief, something standardly referred to, in her view, when we speak of what we believe. This paper focuses on a special response hearers may experience in the context of expressions of belief, a response that may issue in offended rebukes to the speaker. It is argued that this response would be appropriate if both speakers and hearers were parties to what the authors calls a joint commitment to believe a (...) certain proposition as a body. This joint commitment puts speakers under an obligation to refrain from speaking in certain ways, and gives hearers a correlative right to such refraining, and hence a basis for offended rebukes.

The issue of knowing what it means for a group to have collective beliefs is being discussed more and more in contemporary philosophy of the social sciences and philosophy of mind. Margaret Gilbert’s reconsideration of Durkheim’s viewpoint in the framework of the plural subject’s account is one of the most famous. This has implications in the history and the sociology of science—as well asin the history and sociology of philosophy—although Gilbert only outlined them in the former fields and (...) said nothing about the latter. Symmetrically but independently, a historian of science, Mara Beller, has recently challenged Kuhn’s conception of the role of consensus in sciences in a brilliant analysis by carefully studying the history of Copenhagen School of Quantum Mechanics. Not only does she show the role of disagreement and controversies (doubting whether there was any collective belief characteristic in this group of physicists), but she even shakes up the very idea of individual beliefs. Each scientist (Heisenberg, Bohr, etc.) could be seen as divided into several selves. This paper contends that these two conceptions open important new horizons in several domains, especially if they are linked together. The paper assesses this claim in the light of empirical examples like the Vienna Circle, Copenhagen School, and, eventually, Cartesian philosophy. Key Words: plural subject • polyphony • collective briefs • Cartesian argumentation. (shrink)

Margaret Gilbert has defended the view that there is such a thing as genuine collective belief, in contrast to mere collective acceptance. I argue that even if she is right, we need to distinguish two modes of collective belief. On one, a group’s believing something as a body is a matter of its relating to a proposition, as a body, in the same way that an individual who has formed a belief on some matter relates to the (...) proposition believed. On the other, a group’s believing something as a body is a matter of its relating to a proposition, as a body, in the same way that in individual who is forming a belief on some matter relates to the proposition believed.

For almost three decades, Margaret Gilbert has introduced a new account of social facts taking “joint commitments”, not only explicit but also implicit, as the cement of sociality properly understood. Gilbert has used this original account of collective phenomena to clarify a variety of issues, both in the philosophy of rights and in the philosophy of the social sciences. This paper focuses on the latter domain; it argues that although Durkheim and Mauss are central references in her pioneering work, (...) On Social Facts, Gilbert’s model has been underestimated in the fields of sociology and anthropology. This may come from the fact that Gilbert provides the reader with only imaginary examples. To overcome this difficulty, Bouvier investigates several historical examples in two related domains:, the political and the religious. Another reason for this relative lack of interest may come from Gilbert’s very unconventional interpretation of the Durkheimian explanation of social beliefs. Although, on the one hand, her “contractualist” (or Rousseauist) interpretation permits a sharp illumination of certain social facts, it may, on the other hand, impede the recognition of the specificity of other kinds of beliefs, which sociologists and anthropologists—including Durkheim—usually consider as collective beliefs. Bouvier, by contrast, introduces alternative models, illustrating them with similar, although ultimately distinct from previous, historical examples. (shrink)

Margaret Gilbert has recently argued in ProtoSociology against what she called my rejectionist’s view according to which (i) we have to make a distinction between the intentional states of believing and accepting and (ii) genuine group beliefs, i.e. group beliefs that cannot be reduced to the beliefs of the individual members of a group, should be understood in terms of the acceptance of a view rather than of beliefs proper. In this reply I discuss Gilbert’s objections.

Gilbert (1989) and Gilbert and Priest (2013) have argued that paradigmatic conversations involve a collectivity of the conversers who participate in the conversation, in the sense that the conversers put forth and negotiate proposals of propositions to be collectively believed by them. Here I explore the plausibility of this Negotiated Collective Belief (NCB) thesis. I begin by supporting a more basic claim, that the nature of conversation itself entails that a conversation always involves a collectivity of the conversers. I (...) then endorse and supplement Gilbert and Priest’s argument for the NCB thesis. I trace resistance to the thesis to the view that collective belief plays no important role in two primary social ends of conversation, exchanging information and making personal connections. I concede that this is so, but I endorse the view (with roots in Taylor 1985) that collective belief does play an important role in a different primary social end of conversation, the creation of a public space of thought. Thus, the NCB thesis is supported by argument and contributes to an explanation of how conversation fulfills one of its primary social ends. (shrink)

A group is in a state of pluralistic ignorance (PI) if, roughly speaking, every member of the group thinks that his or her belief or desire is different from the beliefs or desires of the other members of the group. PI has been invoked to explain many otherwise puzzling phenomena in social psychology. The main purpose of this article is to shed light on the nature of PI states – their structure, internal consistency and opacity – using the formal (...) apparatus of Dynamic Doxastic Logic, and also to study the sense in which such states are “fragile”, i.e. to identify plausible conditions under which a PI state cascades into a state of shared belief as the result of announcement.

People’s beliefs are influenced by interactions within their communities. The propagation of this influence through conversational social networks should impact the degree to which community members synchronize their beliefs. To investigate, we recruited a sample of 140 participants and constructed fourteen 10-member communities. Participants first rated the accuracy of a set of statements and were then provided with relevant evidence about them. Then, participants discussed the statements in a series of conversational interactions, following pre-determined network structures. Finally, they (...) rated the accuracy of the statements again. The results show that belief synchronization, measuring the increase in belief similarity among individuals within a community from pre-test to post-test, is influenced by the community’s conversational network structure. This synchronization is circumscribed by a degree of separation effect and is equivalent in the clustered and non-clustered networks. We also find that conversational content predicts belief change from pre-test to post-test. (shrink)

Socio-cognitive theory conceptualizes individual contributors as both enactors of cognitive processes and targets of a social context's determinative influences. The present research investigates how contributors’ metacognition or self-beliefs, combine with others’ views of themselves to inform collective team states related to learning about other agents (i.e., transactive memory systems) and forming social attachments with other agents (i.e., collective team identification), both important teamwork states that have implications for team collective intelligence. We test the predictions in a (...) longitudinal study with 78 teams. Additionally, we provide interview data from industry experts in human–artificial intelligence teams. Our findings contribute to an emerging socio-cognitive architecture for COllective HUman-MAchine INtelligence (i.e., COHUMAIN) by articulating its underpinnings in individual and collective cognition and metacognition. Our resulting model has implications for the critical inputs necessary to design and enable a higher level of integration of human and machine teammates. (shrink)

This paper argues for a methodological point that bears on a relatively long-standing debate concerning collective beliefs in the sense elaborated by Margaret Gilbert: are they cases of belief or rather of acceptance? It is argued that epistemological accounts and distinctions developed in individual epistemology on the basis of considering the individual case are not necessarily applicable to the collective case or, more generally, uncritically to be adopted in collective epistemology.

The dynamical hypothesis has served to explore the ways in which cognitive agents can be understood dynamically and considered dynamical systems. Originally used to explain simple physical systems as a metaphor for cognition (i.e., the Watt governor) and eventually more complex animal systems (e.g., bird flocks), we argue that the dynamical hypothesis is among the most viable approaches to understanding pressing modern-day issues that arise from collective human behavior in online social networks. First, we discuss how the dynamical hypothesis (...) is positioned to describe, predict, and explain the time-evolving nature of complex systems. Next, we adopt an interdisciplinary perspective to describe how online social networks are appropriately understood as dynamical systems. We introduce a dynamical modeling approach to reveal information about emergent properties in social media, where radicalized conspiratorial beliefs arise via coordination between user-level and community-level comments. Lastly, we contrast how the dynamical hypothesis differs from alternatives in explaining collective human behavior in social networks. (shrink)

A proof-theoretical treatment of collectively accepted group beliefs is presented through a multi-agent sequent system for an axiomatization of the logic of acceptance. The system is based on a labelled sequent calculus for propositional multi-agent epistemic logic with labels that correspond to possible worlds and a notation for internalized accessibility relations between worlds. The system is contraction- and cut-free. Extensions of the basic system are considered, in particular with rules that allow the possibility of operative members or legislators. Completeness (...) with respect to the underlying Kripke semantics follows from a general direct and uniform argument for labelled sequent calculi extended with mathematical rules for frame properties. As an example of the use of the calculus we present an analysis of the discursive dilemma. (shrink)

This paper addresses how multiple individual credences on logically related issues should be aggregated into collective binary beliefs. We call this binarizing belief aggregation. It is vulnerable to dilemmas such as the discursive dilemma or the lottery paradox: proposition-wise independent aggregation can generate inconsistent or not deductively closed collective judgments. Addressing this challenge using the familiar axiomatic approach, we introduce general conditions on a binarizing belief aggregation rule, including rationality conditions on individual inputs and collective outputs, (...) and determine which rules (if any) satisfy different combinations of these conditions. Furthermore, we analyze similarities and differences between our proofs and other related proofs in the literature and conclude that the problem of binarizing belief aggregation is a free-standing aggregation problem not reducible to judgment aggregation or probabilistic opinion pooling.

Two lines of investigation into the nature of mental content have proceeded in parallel until now. The first looks at thoughts that are attributable to collectives, such as bands' beliefs and teams' desires. So far, philosophers who have written on collective belief, collective intentionality, etc. have primarily focused on third-personal attributions of thoughts to collectives. The second looks at de se, or self-locating, thoughts, such as beliefs and desires that are essentially about oneself. So far, philosophers (...) who have written on the de se have primarily focused on de se thoughts of individuals. This paper looks at where these two lines of investigations intersect: collective de se thoughts, such as bands' and teams' beliefs and desires that are essentially about themselves. There is a surprising problem at this intersection: the most prominent framework for modeling de se thoughts, the framework of centered worlds, cannot model a special class of collective de se thoughts. A brief survey of this problem's solution space shows that collective de se thoughts pose a new challenge for modeling mental content. (shrink)

In everyday discourse groups or collectives are often said to believe this or that. The author has previously developed an account of the phenomenon to which such collective belief statements refer. According to this account, in terms that are explained, a group believes that p if its members are jointly committed to believe that p as a body. Those who fulfill these conditions are referred to here as collectively believing* that p. Some philosophers – here labeled rejectionists – have (...) argued that collective belief* is not belief but rather acceptance. This paper presents several arguments against rejectionism. One has to do with the proper methodology for arriving at an account of belief. Two address rejectionist claims to the effect that collective beliefs* lack key features of belief in general, the features in question being “aiming at truth” and having a particular relation to the will. A fourth notes that there is a phenomenon more apt for the label of “collective acceptance” than is the phenomenon of collective belief*. (shrink)

By applying Mills’ notion of ‘collective memory’, Frost-Arnold argues that an excessive number of false beliefs online (fake news) can condition the memory that we share as a collective. Here I suggest, following Mill’s original characterization of ‘ignorance’, that the construction and maintenance of our collective memory is also vulnerable to some lack of or total absence of true beliefs online. I suggest we must investigate these beliefs attending to two issues: firstly, instances of (...) knowledge that are underrepresented, and secondly, non-propositional forms of knowledge. The first problem is addressed in section 1, where I explore different ways in which some beliefs might not reach the online sphere, due to their minoritarian status. The second problem is my focus on section 2, which entails the consideration of non-dominant forms of knowledge: knowledge-how and knowledge by acquaintance.

Aquí sugiero, siguiendo la caracterización original de ‘ignorancia’ de Mill, que la construcción y mantenimiento de nuestra memoria colectiva también es vulnerable a cierta falta o ausencia total de creencias verdaderas en línea.

El primer problema se aborda en la sección 1, donde exploro diferentes formas en las que algunas creencias pueden no alcanzar el ámbito digital debido a su estatus minoritario. El segundo problema es el foco de atención en la sección 2, donde se consideran formas no dominantes de conocimiento: el saber-cómo y el conocimiento por familiaridad.

At the intersection of social and virtue epistemology lies the important, yet so far entirely neglected, project of articulating the social dimensions of epistemic virtues. Perhaps the most obvious way in which epistemic virtues might be social is that they may be possessed by social collectives. We often speak of groups as if they could instantiate epistemic virtues. It is tempting to think of these expressions as ascribing virtues not to the groups themselves, but to their members. Adapting Margaret Gilbert's (...) arguments against individualist accounts of collective beliefs, I show that individualist accounts of group virtues are either too weak or too strong. I then formulate a non-individualist account modeled after Gilbert's influential account of collective beliefs. A crucial disanalogy between collective traits and beliefs, I argue, makes the success of this model unlikely. I conclude with some questions with which the future work on collective epistemic virtues should engage. (shrink)

Draft as of 2001 of a book chapter a^ppeared in 2005. This paper gives an account of the belief/ acceptance distrinction applied to the issue of collective beliefs and intentionality in terms of the "doctrinal dilemma" proposed by some legal theorists.

In complex societies, there will always be situations in which an individual's deeply held beliefs conflict with the collective norms of the society. When only one individual challenges those norms, the norms generally hold. When challenges come from many individuals, the norms themselves may change. The tolerance for different beliefs will depend upon the political structure of the society and the specific beliefs that are being challenged.The Greek tragedy Antigone is an exploration of the choices that (...) rulers can make regarding such conflicts. They can either tolerate the unpopular and subversive views of an individual or punish the individual in a way that attempts to uphold the existing rules, bolster the... (shrink)

The summativists generally analyze group belief in terms of belief of the majority. The non-summativists counterargue that it is possible for a group to believe that p even if “none” of its members believes that p. In doing so, they usually appeal to hypothetical cases in which groups are “structured” groups like committees, research groups, governments, as opposed to “collective” groups like Finns, America, Catholic Church. In this paper, I raise the objection that non-summativist cases involve summativism. While most (...) contemporary objections to non-summativism tend to be rejectionists, i.e., showing that non-summativist cases involve group acceptance rather than group belief, my objection is newfangled in that it grants non-summativist cases group belief but shows that group belief in such cases is majority belief.

We seem to ascribe mental states and agency to groups. We say ‘Google knows such-and-such,’ or ‘Amazon intends to do such-and-such.’ This observation of ordinary parlance also found its way into philosophical accounts of social groups and collective intentionality. However, these discussions are usually quiet about how groups self-ascribe their own beliefs and intentions. Apple might explain to its shareholders that it intends to bring a new iPhone to the market next year. But how does Apple know what (...) it intends? How do groups get to know their own mental states? This is the question of collective self-knowledge. I argue that collective self-knowledge is a distinct phenomenon that deserves our attention. In particular I suggest: that we should be interested in collective self-knowledge, because our behaviour indicates that we already engage with collective self-knowledge in practice; that groups can collectively avow, which indicates that they have privileged and peculiar access to their own intentional states; and that collective self-knowledge is not reducible to intentional states of individuals and therefore is an independent explanandum.

Belief polarization (BP) is widely seen to threaten havoc on our shared political lives. It is often assumed that BP is the product of epistemically irrational behaviors at the individual level. After distinguishing between BP as it occurs in intra-group and inter-group settings, this paper argues that neither process necessarily reflects individual epistemic irrationality. It is true that these processes can work in tandem to produce so-called “echo chambers.” But while echo chambers are often problematic from the point of view (...) of collective rationality, it doesn't follow that individuals are doing anything wrong, epistemically speaking, in seeking them out. In non-ideal socio-epistemic contexts, echo chamber construction might provide one's best defense against systematic misinformation and deception. (shrink)

The literature on collective belief and collective intentionality has grown rapidly and is now quite extensive. Philosophers have applied the concepts of “collective belief” and “collective intentionality” in a variety of contexts, including political and legal contexts as well as scientific contexts, specifically to model the behavior of research teams and scientific specialties.

In this paper the problem of the relation between belief and acceptance is discussed in view of recent literature on the topic. Belief and acceptance are characterized in terms of a number of properties, which show both the similarities and the dissimilarities between these notions. In particular it is claimed - contrary to some recently expressed views - that acceptance need not be intentional action and that the differences between belief and acceptance do not boil down to the simple view (...) that acceptance, contrary to belief, is based on the agent's direct exercise of his will. Acceptance which is not based on intentional action is shown in the paper to be especially closely related to belief, especially to linguistic belief. Thus if a person is in a non-intentional-ly acquired and held state of acceptance that something p, he also believes that p. Another general difference is that acceptance is language-dependent while there can be non-linguistic belief. Collective beliefs and acceptances are also briefly discussed in the paper Among other things, it is noted that the notion of wide as contrasted with truth-oriented, narrow acceptance is central in the collective case.

Discussion of epistemic responsibility typically focuses on belief formation and actions leading to it. Similarly, accounts of collective epistemic responsibility have addressed the issue of collective belief formation and associated actions. However, there has been little discussion of collective responsibility for preventing epistemic harms, particularly those preventable only by the collective action of an unorganized group. We propose an account of collective epistemic responsibility which fills this gap. Building on Hindriks' (2019) account of collective (...) moral responsibility, we introduce the Epistemic Duty to Join Forces. Our theory provides an account of the responsibilities of scientists to prevent epistemic harms during inquiry. (shrink)

In this paper, I explore what gives collective testimony its epistemic credentials, through a critical discussion of three competing accounts of the epistemology of collective testimony. According to the first view, collective testimony inherits its epistemic credentials from the beliefs the testimony expresses— where this can be seen either as the beliefs of all or some of the group’s members, or as the beliefs of group itself. The second view denies any necessary connection to (...) belief, claiming instead that the epistemic credentials of collective testimony derive from the reliability or truth-conduciveness of the statement that expresses the testimony. Finally, the third view claims that the epistemic credentials of collective testimony derive from the fact that it involves undertaking a collective commitment to trustworthiness, which makes the group susceptible to rebuke and blame if its testimony is not trustworthy. I argue that this last account holds the most promise for preserving what is distinctive about testimonial knowledge while still underwriting a robust epistemology of collective testimony. (shrink)

We present an inferentialist account of collective rationality and intentionality, according to which beliefs and other intentional states are understood in terms of the normative statuses attributed to, and undertaken by, the participants of a discursive practice—namely, their discursive or practical commitments and entitlements. Although these statuses are instituted by the performances and attitudes of the agents, they are not identified with any physical or psychological entity, process or relation. Therefore, we argue that inferentialism allows us to talk (...) of collective intentionality and agency without needing to posit the existence of any sort of collective psychology or mind. (shrink)

Some collective irrationalities, like epistemically and pragmatically reckless Covid skepticism, are especially dangerous. While we normally have incentives to avoid dangerous beliefs, there are cases in which the danger of a belief is valuable. This is not captured by most accounts of motivated reasoning. I argue that Covid skepticism can function as a costly signal (handicap) so as to more effectively communicate social identity and commitment.

Détente or Destruction, 1955-57 continues publication of Routledge's multi-volume critical edition of Bertrand Russell's shorter writings. Between September 1955 and November 1957 Russell published some sixty-one articles, reviews, statements, contributions to books and letters to editors, over fifty of which are contained in this volume. The texts, several of them hitherto unpublished, reveal the deepening of Russell's commitment to the anti-nuclear struggle, upon which he embarked in the previous volume of Collected Papers ( Man's Peril, 1954-55 ). Continuing with the (...) theme of nuclear peril, this volume contains discussion of nuclear weapons, world peace, prospects for disarmament and British-Soviet friendship against the backdrop of the Cold War. One of the key papers in this volume is Russell's message to the inaugural conference of the Pugwash movement, which Russell was instrumental in launching and which became an influential, independent forum of East-West scientific cooperation and counsel on issues as an internationally agreed nuclear test-ban. In addition to the issues of war and peace, Russell, now in his eighties, continued to take an interest in a wide variety of themes. Russell not only addresses older controversies over nationalism and empire, religious belief and American civil liberties, he also confronts head-on the new and pressing matters of armed intervention in Hungary and Suez, and of the manufacture and testing of the British hydrogen bomb. This volume includes seven interviews ranging from East-West Relations after the Geneva conference to a Meeting with Russell. (shrink)

Propositional attitudes, such as beliefs, desires, and intentions, can be attributed to collective agents. In my paper I focus on cognitive attitudes, and I explore the various types of collective beliefs. I argue that there is a whole spectrum of collective beliefs, and I distinguish between two extremes: the weak opinion poll conception and the strong agreement-based conception. Strong collective beliefs should be understood in terms of the acceptance of a proposition rather (...) than of belief proper. They are not purely epistemic and involve practical considerations. To believe that p collectively in the strong sense is to adopt a policy to use that proposition in the group’s deliberations about future actions. (shrink)
